Definitions

  • the invention relates to a catheter, in particular a venous catheter, with at least one identifying thread that weakens in the longitudinal direction in the catheter wall and weakens X-ray radiation.
  • identification threads are known.
  • the identification threads are used to determine the exact position of the catheter in the body of the respective patient when working under X-ray control.
  • the invention has for its object to improve the described, known catheters such that the aforementioned risk is eliminated and reliable control at all times the completeness of the catheter is made possible and that the reliable detection of the respective position of the catheter in the body of the respective patient is ensured.
  • the identification threads have a predetermined number of irregularities arranged at corresponding distances from the distal end of the catheter, and in that the distances between the distal end of the catheter and the distal last irregularities and the non-uniformities which follow one another in the longitudinal direction match. Because of the special arrangement of the non-uniformities, characterized by a predetermined number and predetermined distances, it can be checked at any time and in particular also during the operation whether the catheter is complete or in the correct position. If the control shows that a part of the catheter has been sheared off or torn off, relief measures can be initiated immediately. If the control shows that the catheter is not in the desired position, its position can be corrected.
  • the non-uniformities can consist of widening of the identification threads, of interruptions in the identification threads, or of ring-shaped, X-ray radiation-weakening regions arranged in the region of interruptions of the identification threads in a cross-sectional plane of the catheter.
  • the first interruptions when viewing the catheter from the distal end of the catheter can be characterized by a ring, the second interruptions by two parallel rings, etc. It It is also advisable to mark the distal end of the catheter with an annular area that weakens X-rays.
  • FIG. 2 shows the end section according to FIG. 1 in cross section
  • FIG. 4 shows a further embodiment of the end section according to FIG. 1.
  • FIG. 1 shows a simplified representation of a venous catheter 1 which, for localization under X-ray control, is provided with three identification threads 2 running in the longitudinal direction in the catheter wall and attenuating X-ray radiation.
  • the identification threads 2 are evenly distributed over the circumference of the venous catheter 1, as can be seen particularly clearly from FIG.
  • a catheter despite the identification threads due to the overlay of shadowing structures (bones and soft tissues such as heart and lungs) are also difficult to locate under unfavorable circumstances.
  • shadowing structures bones and soft tissues such as heart and lungs
  • the identification threads 2 have a predetermined number of irregularities arranged at corresponding distances from the distal catheter end 3, which are explained in detail below.
  • the distances between the distal catheter end 3 and the distal last irregularities and the consecutive irregularities in the longitudinal direction match.
  • three such irregularities can be provided at distances of 10, 20 and 30 cm from the distal end 3 of the catheter.
  • the non-uniformities consist of interruptions 4 in the identification threads 2.
  • FIG. 3a shows an exemplary embodiment in which the non-uniformities are formed by widenings 5 of the identification threads 2.
  • FIG. 3b shows an exemplary embodiment in which an annular area 6 which attenuates X-rays is additionally provided in the area of the interruptions 4 in a cross-sectional plane of the venous catheter 1.
  • FIG. 3c shows an exemplary embodiment in which an annular region 7 which attenuates X-rays is additionally provided at the distal end 3 of the catheter.
  • FIG. 4 finally shows an external view of a venous catheter 1, as it were without X-ray radiation, so that the identification threads 2 explained above cannot be recognized.
  • an optically visible end marking is provided on the distal end 3 of the catheter, which in the illustrated case consists of a plurality of colored rings 8 arranged in parallel and at short mutual distances, each of which has a width of approximately 1 mm, for example, and a mutual distance of likewise 1 mm are arranged, while the annular region 7 forming an X-ray-effective end marking preferably has a width of approximately 5 mm.

Abstract

Le catheter, notamment catheter veineux, presente des fils d'identification (2) attenuant les rayons X, disposes longitudinalement dans la paroi du catheter. Ces fils permettent le controle et la localisation du catheter (1) dans le corps du patient. Des irregularites (4, 5, 6) sont menagees en nombre predetermine en direction longitudinale et a distances prefixees de l'extremite distale (3) du catheter. Ces irregularites peuvent consister en elargissements (5) ou en interruptions (4) des fils d'identification. Des zones annulaires (6) attenuant les rayons X, disposees dans la region des interruptions (4), peuvent aussi etre prevues. Un nombre variable de ces zones annulaires (6) peut etre arrange avec les differentes irregularites des fils d'identification. Une partie annulaire attenuant les rayons X peut etre menagee a l'extremite distale du catheter (3). Elle peut etre formee de plusieurs rondelles placees parallelement cote a cote, visibles optiquement (p. ex. colorees).
